Answers
Part A
For this part, I'm assuming your teacher implies that we ignore the door, windows and rectangular opening. It seems like parts B and C cover this aspect.
There are 2 walls that are 20 feet by 10 feet. Each is 20*10 = 200 sq ft, so both opposite walls are 2*200 = 400 sq ft.
Then there are 2 more walls that are 15 ft by 10 ft. Each has area 15*10 = 150 sq ft, and doubles to 2*150 = 300 sq ft.
The total wall area (ignoring any openings/doors/windows/etc) is 400+300 = 700 sq ft.
Another way to get this answer is to find the perimeter of the floor rectangle to get 2(L+W) = 2(20+15) = 2(35) = 70. Then multiply this with the height of the room to get 70*10 = 700
Answer: 700 square feetNote: This ignores the windows/doors/any other opening
====================================================
Part B
Useful info to focus on:
Fact1: Along one of the long walls, there are three windows that each measure 3 feet by 8 feetFact2: Along one of the short walls, there are two windows that each measure 3 feet by 8 feet.Fact3: Along the other long wall, there is a rectangular opening that measures 7 feet by 8 feet.There's no mention of a door (either front door or interior door to another room). Instead, your teacher talks about a rectangular opening which I'm assuming is the walkway to perhaps the kitchen and/or hallway or something. Though this rectangular opening might be part of or entirely the front door. It's not clear what your teacher means here. I'll just forget about the door part.
Fact1 and fact2 tell us we have 3+2 = 5 windows of 3 ft by 8 ft. Each window has area 3*8 = 24 sq ft. Five of them give 5*24 = 120 sq ft
Fact 3 says we have a rectangular opening of area 7*8 = 56 sq ft.
The total area of all items mentioned is 120+56 = 176 sq ft
Answer: 176 sq ft====================================================
Part C
We subtract the results of the previous parts A and B
wall area to paint = A - B = 700 - 176 = 524 sq ft
We're told that "The cans of paint Kamrie will purchase cover 415 square feet." So we'll divide the total area over the area per can.
524/415 = 1.26265 which is approximate
Round up to the nearest whole number. We don't round down to 1 can because we'll come up short. Instead we round to 2 paint cans. Having extra leftover paint is handy in case Kamrie made a mistake somewhere.
For this entire problem, I'm ignoring the ceiling and focusing on the walls only.

During a sale, a baseball team allows people to buy either a classic ticket (C), or an autograph event ticket (A). Suppose two customers buy one ticket each. What is the sample space for this action? Drag and drop the choices into the box to correctly complete the table. If an item is not in the sample space, do not drag it to the table.
Answers
Sample size is the number of subjects that are included in research or survey. The sample space for this action is CC, CA, AC, and AA.
What is a sample size?Sample size can be defined as the number of subjects that are included in research or survey.
As it is given that there are two customers, and each of the customers buys any one of the two tickets, a classic ticket (C), or an autograph event ticket (A).
Now, as each of the customers has two choices, therefore, the sample space for this action can be written as,
CC - When both of the customers buy a classic ticket.
CA - When the first customer buys a classic ticket(C) while the other buys an autograph event ticket (A).
AC - When the first customer buys an autograph event ticket (A) while the other buys a classic ticket(C).
AA - When both of the customers buy an autograph event ticket (A).
Hence, the sample space for this action is CC, CA, AC, and AA.

find the surface area
Answers
Answer:
70 inches²
Step-by-step explanation:
We can break this shape up into 5 different shapes.
Two triangles, and three rectangles.
The three rectangles will be A = L * W and are all the same size,
A = L * W
A = 3(L * W)
A = 3(10 * 2)
A = 3(20)
A = 30 inches²
Now, we need to find the area for the two triangles. Usually, you would take the base times the height and divide by two, but since we have two triangles of the same size we do not need to divide by two,
A = B * H
A = 10 * 4
A = 40 inches²
Last, we will add the two areas for the triangles and rectangles together,
40 inches² + 30 inches² = 70 inches²
The tallest tree in the world is 379 feet tall. How tall will each of the trees be in the year 2030 if their models continue? Is this reasonable for each tree?.
Answers
Models are patterns that are used to predict measurements and populations
How to model the treeThe question is incomplete, as the model and the dataset to model that growth of the tree are not given.
So, I will give a general explanation
If the model of the tree follows a linear model (e.g y = 2x + 3), then the model is not reasonable.
This is so because, population and growth cannot be measured by a linear model
However, if the growth of the trees follow an exponential model (e.g y = 2(3)^x), then the model is reasonable

Find the new concentration of a solution if 25. 0 mL of water is added to 125. 0 mL of 0. 150 M NaCl solution. What is the final volume? mL.
Answers
Part A: The final volume of the new solution is 150 mL.
Part B: The concentration of the new solution is 0.125 M.
What is the volume?The volume of liquid is defined as the amount of liquid in a three-dimensional container. Volume is the quantity of three-dimensional space occupied by a liquid.
Given that the molarity of NaCl solution is 0.150 M, the volume of NaCl solution is 125 mL, the volume of water added is 25 mL.
Part A:
The final volume of the new concentrated solution is calculated as given below.
[tex]V = 125 + 25[/tex]
[tex]V = 150 \;\rm mL[/tex]
The final volume of the new solution is 150 mL.
Part B:
The mole of the NaCl solution is calculated using the molarity formula.
Molarity of NaCl solution = 0.150 M
Volume of NaCl solution = 125mL or 0.125 L
Molarity = Mole of NaCl solution / Volume of the NaCl solution
[tex]0.150 = \dfrac {Moles}{Volume}[/tex]
[tex]0,150 = \dfrac {Moles}{0.125}[/tex]
[tex]Moles \;= 0.01875[/tex]
The moles of NaCl solution is 0.01875 mole which remains same when water is added. Thus, the molarity of the new concentration can be calculated as given below.
Molarity = Moles of NaCl / Volume of new solution
Molarity = [tex]\dfrac {0.01875}{0.150}[/tex]
Molarity = 0.125 M
Hence we can conclude that the concentration of the new solution is 0.125 M.

What is the length of line HI and IJ
Answers
Point H is even with point E and I is exactly half way in between E and F. EF = 40 half of that is 20. This also works with HG, BC, and JK.
HI and IJ are the same length so both are 20mm
Answer:
HI = [tex]4\sqrt{41}[/tex] , IJ = [tex]4\sqrt{41}[/tex]
Step-by-step explanation:
The number of AB spaces is 15, the BC is 20, and the CD is 15. Looking at the given length, you can see that it is twice the number of cells.
If you draw a line perpendicular to the line HG in I, it becomes a right triangle. The lengths of HI and IJ can be calculated using Pythagoras on a right triangle.
Suppose that the vertical line is L.
HL = 10
IL = 8
(HI)² = (HL)²+ (IL)² = 10²+8²=164
HI = [tex]2\sqrt{41\\[/tex] -> (It's twice the number of spaces.) -> HI = [tex]4\sqrt{41}[/tex]
IJ can be obtained in the same way.
IJ = [tex]2\sqrt{41\\[/tex] -> (It's twice the number of spaces.) -> IJ = [tex]4\sqrt{41}[/tex]
